Pocket Book Chess puzzles / tactics / training

Hello

I'm looking for a little book (paperback?) only with chess exercice tactics / chess puzzles to bring every where. 

Not a 10inch book. 

Thanks you very much. 

This one is pretty small.

If that one is too advanced, Bobby Fischer Teaches Chess is a small paperback that might work for you. And there are probably phone apps for basic tactics.

This one is 5x7, a pocket book. I think mine is smaller than that even but I am too lazy to get up and find it.

Lev alburt tactics pocket books are fine...

I see... then maybe have have a look at Practical Chess Exercises: 600 Lessons from Tactics to Strategy

It's a puzzle book with not only tactics but also strategy, endgame, defense problem. Diagrams are on the left page and answers on the right and you can just close them with a sheet of paper and don't have to flip back and force.

This book by Lev Alburt would be an excellent choice - it is much more instructive than the typical puzzle book....and it is 5x7 inches...

And don't be scared by the cover - it is NOT cheap porn - it is chess!

ahahahahaha
